VENTILATED SHOE.

SPECIFICATION forming part of Letters Patent No. 660, dated October Applioation filed May 12, 1900.

To all whom it may concern.-

Be it known that 1, CHARLES K. SHAROOD, of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Ventilated Shoes, of

which the following is a specification.

This invention relates to shoes having provision for the admission and egress of air to the interior of the shoe by way of the bottom thereof; and it has for its object to provide a simple construction whereby the desired result may be attained.

The invention consists in theimprovements which I will now proceed to describe and [5 claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a longitudinal section of a shoe embodying my invention. Fig. 2 represents a bottom view of the shoe shown in Fig. 1, the outer sole and heel being removed. Fig. 3 repre sents a section on line 3 3 of Fig. 2. Fig. 4 represents a section on line 4: 4 of Fig. 1.

The same reference characters indicate the same parts in all the figures.

In the drawings, a represents the inner sole, and b the outer sole, of a boot or shoe.

0 represents the usual heel-stiffener, andcl represents the heel portion of the upper.

The construction here shown represents a welted shoe, 6 being the welt, which is stitched to the upper and inner sole by the usual inseam-stitches and to the outer sole by the usual fair stitches. The invention is not limited, however, to a welted shoe, but may be applied to a shoe of any other construction.

f f f f represent spacing-strips which are interposed between the inner and outer soles and are formed and arranged to create lougitudinal air passages or spaces 9 g g g between the inner and outer soles. The strips 9 are preferably pieces of leather cemented or otherwise secured to a sole-shaped piece of canvas or other suitable material which is cemented to the under side of the inner sole.

h h represent perforations in the inner sole, communicating with the interior of the shoe and with the air-passages g g.

2' represents an air-tube, preferably of rub- 0 her, one end of which is interposed between the heel portions of the inner and outer soles Serial No- 16,4:62- (No model.)

and communicates with the central air-space g. The other end of the tube f is extended upwardly and located between the heelcounter c and the heel portion d of the upper. Said heel portion 01 is provided with an air opening j, which is preferably formed by punching a hole through the upper and in serting an eyelet j in said hole to form the wall of the opening j. The tube 1' communi 6o cates with the openingj, so thatthere is a con= tinuous passage for the entrance of external air to the interior of the shoe through the openingj, the tube i, the air-spaces 9 between the inner and outer soles, and the perfora- 65 tions 71 in the inner sole. While the shoe is in,the process of manufacture, the tube 1' is preferably filled temporarily with a piece of flexible cord to prevent it from being col lapsed by the pressure exerted on the shoe by the various operations to which it is subjected, one end of the cord extending through the opening j, so that it may be removed after the shoe is completed, thus leaving the tube 1' unobstructed.

The heel-stiifener c is preferably provided with a shallow groove or depression in its outer surface to receive the inner side of the tube 71, this depression tending to maintain the tube in an open or unobstructed condition. The portion of the upper that covers the tube 2' is preferably provided with a reinforcing-strip d.

I claim- A boot or shoe having a perforated inner sole having a sole-shaped piece of flexible material secured to the under side thereof, spacing-pieces comprising strips secured in a longitudinal position to said piece of flexible material, said spacing-pieces being interposed between the inner and outer soles and forming air-passages communicating with the perforations in the inner sole, and an air-tube communicating at one end with said air-passages and at the other end with an opening 5 in the heel portion of the shoe.

In testimony whereof I have affixed my signature in presence of two witnesses.

CHARLES K. SHAROOD.
